Model airplanes not included. Note the stage has been rotated to adjust sheer angle on specimen, and camera rotated to compose p...

First Go At DIC Imaging

My camera adapter finally arrived, and I wasted no time trying it out, as this is something I've eagerly anticipated for many moons. Just I suspected, there is a LOT of versatility in DIC imaging, lots of things to adjust and play with. Besides the usual balance of shutter speed, ISO, and condenser ...

Re: loupe purchase advice

For my money, it's best to always go with the widest field, highest eyepoint oculars available whether you wear glasses or not. But to answer your question, I can't see where you'd have any problem with the Belomo. I use mine while wearing my readers, and just now tried it again to be sure before po...

Re: loupe purchase advice

I did a little messing around to see if I could answer some questions. First, I tried a reversed 15x eyepiece as a loupe, and found it a pretty poor one with tons of spherical aberration, only sharp in the center 1/3 or so. Next, I compared the 10x Belomo loupe to a couple of 10x microscope eyepiece...

Re: loupe purchase advice

I have been using loupes since the late 70's for photography (back when we would examine slides, negatives, and prints), rock & minerals, and for just about anything and everything else. Have also seen a zillion loupe discussions of forums. It's one of those things where if you ask ten people, you g...

Yep, I'd have to call that one of the most remarkable photomicrographs I have ever seen.

I like the little short guy on the end! I can see where you may be tempted to do something to make the set look more uniform, but the difference in configuration is much more interesting to my eye. Also love the tools and work space shots! I also have several sets of gunsmith's screwdrivers, and par...

I'm pretty stoked - finally got busy and converted my travel scope from 20W halogen illumination to self-contained, LED. I use an AO 10 (shorthand for American Optical Series 10) as a travel scope. Not field scope, but travel scope, that I take along to use when I visit places for weeks on end as I ...
